If the default skin looks too grayish for you and you want it darker, here is my first skin. I carefully tuned the colors and I even made popup browser translucent. (HSV: 200°, 10%, x%)
Since I like customization and this epic synth, I can take effort to make some skins (don’t expect me to make more).
p.s. Maybe a new topic for sharing skins is a good idea. I’m still aware that we cannot ask the dev for some features and bug fixes on the skin designer yet.
